The force of gravity between the apple and the baseball is 3.335×10¯¹¹ N
The following data were obtained from the question given above:
Mass of apple (M₁) = 1 Kg
Mass of baseball (M₂) = 2 Kg
Distance apart (r) = 2 m
Gravitational constant (G) = 6.67×10¯¹¹ Nm²/Kg²
<h3>Force (F) =? </h3>
The force of gravity between them can be obtained as follow:
Therefore, the force of gravity between them is 3.335×10¯¹¹ N

Answer:
Length will be 0.491 nm
Explanation:
We have given wavelength of the photon
Plank's constant
We know that energy of the photon is given by
We know that energy of photon is also given by
One of two things is true about this question: EITHER it can't happen
as you've described it, OR you've left out some vital information.
-- IF the first stone was thrown downward with an initial speed and the
second one was dropped from rest 1 second later, then the second one
can never catch up with the first one, and they can never hit the water together.
-- IF the first stone was thrown downward with an initial speed, AND the
second one was released 1 second later, AND they actually do hit the
water together, THEN the second stone must have been given an initial
downward speed greater than 2 m/s, otherwise it could never catch up
with the first one.
Note:
The masses and weights of the stones are irrelevant and not needed.
=======================================================
An afterthought . . . . .
If the first stone was tossed UP at 2 m/s . . . that could be the meaning of the
prominent plus-sign that you wrote next to the 2 . . . then it rises for (2/9.8) second, then begins to fall, and passes the mountain climber's hand on the way down (4/9.8) second after he tossed it, falling at the same 2.0 m/s downward.
From there, it still has 50m to go before it hits the water.
50 = 2 T + 1/2 G T²
4.9 T² + 2 T - 50 = 0
T = 3 seconds
The first stone hits the water 3 seconds after passing the mountain climber's hand on the way down at a downward speed of 2.0 m/s. In that 3 seconds, it gains (3 x 9.8) = 29.4 m/s of additional speed, hitting the water at (29.4 + 2) = 31.4 m/s .
This is all just a guess, assuming that the 2.0 m/s was an UPWARD launch.
Maybe I'll come back later and calculate the second stone.
Answer:
The rate of the reaction would increase.
Explanation:
The activation energy in chemistry and biology is the energy that a system needs before it can start a certain process. The activation energy is usually used to designate the minimum energy necessary for a given chemical reaction to occur. For a reaction to occur between two molecules, they must collide in the correct orientation and have a minimum amount of energy. As the molecules approach, their electron clouds repel. This requires energy (activation energy) and comes from the heat of the system, that is, the translational, vibrational energy of each molecule.
The activation energy of the reaction corresponds to the energy necessary for the reaction to be carried out with less reagent energy. The lower the activation energy of a reaction, the higher the speed of the reaction.
A reaction is called exothermic when it provides for the medium a higher energy than is necessary to reach the activated complex.
When a reaction is endothermic, it provides for the environment a lower energy than is necessary to reach the activated complex.
Catalysts are substances that decrease the activation energy for a given reaction, without altering its ΔH. The catalysts do not alter during the reactions.
